Marines did not move at all

[vwxyzjn]

Hi,

I am conducting similar research on defeating the roaches and I was trying to run your code... But the marines just stay at where they were, and almost it almost seemed that the game just froze. Check out the following picture.

I simply use python PySC2_A3Cagent.py to run it. Should I pass some kind of parameters?

Thanks.

Nope no parameters are needed. I think it might be a Windows thing, probably the threading. I've only tried it on Mac and Linux so far. I'll try to install SC2 on my Windows setup and run the script. Can I check if there are any error messages? I assume the Remaining Time counter in the screenshot doesn't run either right?

@greentfrapp Thanks for replying. There is no console message at all actually. So no, the remaining time counter did not show up.

Oh I meant the Remaining Time counter in the Starcraft 2 screens. Anyway thanks for highlighting this! I'll look into it but it might take awhile because I seem to be having trouble installing Starcraft2 on my Windows. Meanwhile, let me know if you manage to figure out the problem!

@greentfrapp I made it working.

It was the multiprocessing that's doing the harm. If I change num_workers = 1 instead of multiprocessing.cpu_count(), then your program is able to run.

    with tf.device("/cpu:0"): 
        global_episodes = tf.Variable(0,dtype=tf.int32,name='global_episodes',trainable=False)
        trainer = tf.train.AdamOptimizer(learning_rate=1e-4)
        master_network = AC_Network('global',None) # Generate global network
        num_workers = 1 # Set workers to number of available CPU threads
        workers = []
        # Create worker classes
        for i in range(num_workers):
            workers.append(Worker(i,trainer,model_path,global_episodes))
        saver = tf.train.Saver(max_to_keep=5)

Okay great! Thanks! I'll try to push a version that fixes that soon. Meanwhile, I recommend that you try to set num_workers to > 1 at least, to take advantage of the asynchronous component.

Hi @vwxyzjn, can you try the latest PySC2_A3C_AtariNet.py script and see if that works in Windows? I've replaced the multiprocessing module with psutil for retrieving the cpu_count. Sorry I haven't been able to install SC2 on my Windows yet so I haven't been able to try that out on Windows.
